'@max(64) boxes: []Box' on a property's or a state's field is a promise: the grow path of a push to
that field (only the grow path, so nothing is paid until it doubles) checks it, and growing past n is
reported by the fence - 'PoolState.boxes grew past its @max(16) (it holds 16)' - counted under
count, said under warn, and under fail (a headless or dev build's default) the run ends with exit 87.
Mem.over("what") is the same for a package's own table: ludic.base's StrTable past its most
(sb_intern) and ludic.ui's memo past three quarters of MM_CAP no longer quietly copy per call. The
census counts overflows.

ludic deps --births lists every site the escape analysis finds kept by nothing and not the frame
arena's - boot and load code, a function spanning frames, frame code with the arena off - which is
made and dropped and never given back; birth_leaks is a number --check ratchets. A text used up by +
or == where it is made is freed at once and not counted; nor is what @alloc_ok covers.

Seventeen inline messages (allocation failures, missing conversions, the no-pipeline and compressed-
target warnings, resize and swapchain lines, the test-frame camera line, DLSS evaluate, shadow memory,
stream and terrain debug, the water test) are each a function of their own under @alloc_ok, taking
numbers, so the paths that say them hold no site. post_measure's two 1x1 exposure targets are made in
post_init and DLSS's evaluate structs in gsl_init; DLSS's camera up is a state field. The lists play
pushes into (retired, free ranges, spare ids, the per-buffer gpu flags, the stage and the actor spares)
get their room at start-up (gvk_room_*, actor_room), so a push fits. Compiled (steady).

keep(x) copies a string, a slice (header and elements) or a record (shallow) onto the heap; intern(s)
hands back one heap string per distinct text from a fixed table in the runtime (FNV-1a, 65536 slots,
copied the first time; past 49152 only copied). Both are how frame code keeps what it made on purpose:
the escape analysis takes the copy as the heap's and leaves the argument LOCAL.
The analysis now records why a class escapes (the store, the event, the global it reached) and
ludic deps lists every allocation frame code makes and keeps - fkeep lines, 'ludic deps --keeps',
the frame_keeps number --check ratchets - leaving out what is under @alloc_ok and a push's growth
(25.5's capacities). --arena-strict (or 'arena strict') makes each an error naming the store, before
anything is emitted. A test: a template stored into a state is the one error; keep and intern of the
next two, an @alloc_ok push and a scratch temporary are not; 195 frames of arena resets under
R3D_ARENA_CHECK=1 later the kept and interned texts read as made, and intern gives the same string.

Render3dState's cam_planes, gpu_u_tmp, q_scratch, ov_nine_buf, the caster test's four points,
ter_bw, ter_scr and water_saved default to their buffers (as ludic.anim's clip state does), so the
lazy starts in cam_planes_update, gpu_tmp, terrain_height_smooth, ter_scratch, the water pass and
gvk_startup_state go. q_euler makes its views of q_scratch once (guarded on the view now). Compiled.

Behind ludicc --arena (or 'arena on' in the program's package.ludic): the escape analysis runs and a
LOCAL site's allocation raises @lp_want for that one call, so it comes from the frame's arena. Two
halves in one mmap reservation (R3D_ARENA_MB each, 256 by default), bump-allocated with a 16-byte
size header, flipped at each frame mark: a frame's scratch is good through the next frame, then its
half is started again (R3D_ARENA_CHECK=1 fills it with 0xDD first). The heap takes over when no frame
is running, off the main thread, or past the half's end; lp_free ignores an arena block and
lp_realloc copies one out. R3D_ARENA=0 turns it off at run time; the census reports each half's
high-water mark. A program that builds text, a list and a record per frame: 29998 heap blocks made
and 18002 freed without it, 8 and 8 with it and 544 bytes of scratch a frame, the same output.
A dispatch's 'new' fills the queue's kept record (E_NEW.b), so 25.2 no longer counts it and 25.3
treats its fields as kept. '@frame' is keyed by property and field: a 'run' field is a root only in
a property that marks it, and 'tick' stays a System's.

shadow_pass's fbo status and probe block, shadow_bind's two location prints, layer_partition_lods'
LOD line and layer_update's dump are each a function of their own under @alloc_ok (debug switches
only), so the passes themselves hold no allocation site. Compiled (steady).

The renderer starts itself from the first frame (gpu_select), so the device, its tables, the
manifest and programs, grass, shadows, sky, terrain textures and the actor pool read as frame
allocations: each is @alloc_ok as start-up, with gvk_fail (a failure) and the actor census and
texture dump (debug switches). ov_nine's four corner/uv arrays are one floats(16) made in
gvk_startup_state; ac_in_light's four points are made there too. Compiled (steady, and ludic deps
over main 4316ff97).

Each morning's repopulation made a new WildAnimal (and the game a new drawing, actor and skeleton,
keyed by an ever-rising key) for every animal that had gone. A legend's record is never taken, nor
one still in a crowd. reuse_test: a hundred removes and makes are one record.

emit_escape.ludic: every value is in a class, joined by flow edges (a let, an assignment, an argument
into its parameter, a result into the call) and store edges (a field, an element, a push). HEAP (a
parameter, a state, a global, what an unknown call hands back) flows forward; ESC (stored into
something HEAP, into a global, into an event's fields or named values, handed to an unknown callee)
flows backward, and from an ESC or HEAP target along a store. A load is its base's class. A site that
is neither ESC nor in a function reaching Mem.frame is LOCAL (Node.uns = ES_SCRATCH). ludicc
--escape-report prints each site and the totals; nothing is emitted differently yet - the arena that
allocates the LOCAL sites is next.
@alloc_ok on a generic now covers its instances (kept_push$NetFact is under kept_push's), and a
statement's @alloc_ok is carried on the node (Node.uns), so a generic's clone keeps it.

A frame holding a new peak of facts made a record and grew the free list; now nothing is made until
64 are held at once. The two record-count tests hold the 64.

ludic deps --allocs (25.2) found npc_pick_name making a list of the body's names at every spawn and
np_left making a new list of the recent names at every retire.

actor_own_skin(a) gives an actor its own clone of its model's skeleton and actor_release frees it
(skin_clone_free: the pose, matrices, views and scratch the clone made; the rest data stays its
source's). gvk_startup_state, at the end of gvk_init, makes the scratch and tables a draw used to
make on first need (gvk_tmp_buf, the pipeline fast cache, the set key and per-program uniform
offsets pre-sized to 4096 programs, skip/seen/size words, spare and retired lists, the grass cull's
words), and those frame paths no longer start them. Compiled (steady).

@alloc_ok with its reason on what is made once per resource and kept (textures, programs, samplers,
views, layouts, memory blocks, the pipeline cache in gvk_pipe_build), on resize and swapchain
remakes, on screenshots and dumps, on a world being set up (streams, layers, water, post, bakes), on
loads (gltf_load, skin_load, tex_load*, png_decode, fonts) and on R3D_PROF / drawstats.
gltf_cached's hit path is its own and makes nothing; the miss (gltf_cached_load) is declared.
m4_look_at (now over m4_look_at_xyz) and m4_inverse work on scalars, and cam_update makes no scratch.
Left: lazy first-use starts, error and debug prints, and scratch made and freed each call (churn,
plan 25.3). Compiled (steady, and ludic deps over the game).

A field declared '@frame run: fn(...)' makes every function stored in it a frame root, as a System's
tick is. @alloc_ok("why") before a statement takes that statement out of frame_allocs and makes what
it allocates declared at run time; a function holding one keeps the fence's scope depth and puts it
back at its return, so a return inside the statement cannot leave the scope open. @alloc_ok above
'export function' was lost - export parses the declaration one call down - and is now carried to it.
